Orhan Koylu developed the Volunteer Shift Instruction Workflow for the oss-slu/shelter_volunteers repository, enabling staff to add and manage shift instructions through a React-based UI with an EditRequestModal and a toggle for displaying shelter instructions on upcoming shifts. He improved the reliability of service shift updates by enhancing error handling, standardizing API responses, and validating volunteer counts using Python, Flask, and MongoDB. Orhan also implemented user-facing feedback with toasts and cleaned up JSON encoding. His work addressed issues with data integrity and miscommunication, resulting in a more robust backend and a clearer, more efficient experience for volunteers and staff.
